Montana Cannabis Laws

Montana has a long history of legal cannabis legalization, starting in 2004 with medical. But then back-and-forth made Montana medical marijuana harder to get. In the US state of Montana, marijuana has been legal for both medical and recreational use since January 1, 2021, when Initiative 190 came into effect. Prior to the November 2020 initiative, cannabis was illegal for recreational use from 1929. Medical marijuana was legalized in 2004 in an attempt to vote. [1]

The labeling and packaging rules apply to marijuana and marijuana products that are for ultimate adult-use cannabis sales to a consumer, registered cardholder, or their designated purchasers. Please note: cannabis legalization is not currently national and this blog and the policy information in it is specific to Montana. 

Montana Cannabis Laws - Marijuana Packaging Requirements

Protect: Cannabis packaging must protect the product from contamination and not impart any toxic or deleterious substances to the marijuana products. This means you should use FDA approved barrier packaging, like flexible barrier packaging.

Resealable:  If the package contains more than one serving, it needs to be resealable, meaning it needs to have a recolorable zipper.

Not 'primarily' appeal to children.

You cannot include depictions (pictures, illustrations, or other graphics) of children. 

Your graphics and packaging, cannot include images, drawings, or other portrayals of objects, images, celebrities, or cartoon figures that "primarily appeal to children" or are "commonly used to market products to children". This can be dicey territory, but generally avoid all cartoon characters.

Finally the state includes a subjects catch all provision that doesn't allow packaging or labeling that otherwise has special attractiveness for children beyond the general attractiveness for adults.

Use of Trademarks

McDowells Montana Cannabis Laws

The regulations prohibit trademark infringement. So unfortunately you can't be the McDowell's of Montana Cannabis.  and this section is similar to several other states like Maine and Oklahoma, the state of Montana very much limits the use of trademarks or graphics that resemble trademark, or and this is a bit of a distinction  between it and other states, which "bears any reasonable resemblance to" the trademarked or "characteristic packaging of any commercially available product, including but not limited to candy, snacks, baked goods, or beverages. 

 In this way it appears the legislative intent of this section was to prevent confusion of marijuana products with non-medicated products, and not encourage knock off marijuana versions of unmedicated products. 

Exit Packaging

Montana is a exit bag state. Exit bags or exit packaging is a required for all marijuana and marijuana products at the point of sale. This means that at the point of purchase all marijuana products have to be put in "exit packaging" which is:

  • Child Resistant
  • Opaque
  • Includes required warnings. 

Child Resistant Standard in Montana

In the state of Montana the child resistant standard is found in ARM 42.39.102(8). The standard of child resistance is defined by reference to the Federal Consumer Product Safety Commission (CPSC) and 16 CFR 1700.20. 

Labeling Requirements for Legal Marijuana

  • Font: The state of Montana merely requires a "legible font" but do provide some examples (Times New Roman, Arial, or Helvetica) , which if we were you, we'd stick to what they suggest. 
  • Font Size: The primary font size requirement is that the letter "o" must be at least 1/16th" in height. This is very unusual and as far as we can tell, specific to Montana. Most states that prescribe font size use standard language like "6pt font".

  • English Language: You must put all required text in English. There is no requirement for dual language warnings.  

PRO-TIP: For required warnings, use Times New Roman, in a minimum 4mm font size (Adobe Illustrator).

Montanas Universal Marijuana Symbol Montana Cannabis Laws

The state requires the symbol will be at a minimum .33" x.33" in size.

States with a lot of open land, natural resources, and a fertile environment for agriculture, such as Montana. There are about 28,000 ranches and ranches in the state, each averaging 2,000 acres. Cannabis farms have sprung up all over the state over the past few years. In 2019, Montana farmers planted a total of 22,000 acres of hemp across the state, averaging half a million dollars per farm. Medical marijuana, like cannabis, is not accessible to everyone and cannot be thrown in a jar.

If one doesn't adhere to these laws, it could result in a punishable misdemeanor, fine, or felony.
